Description

Bromochlorophenol Blue Sodium Salt is a high-purity indicator dye widely used in analytical chemistry. Its primary value lies in its sharp color change, which provides a reliable visual endpoint for precise pH and complexometric titrations. This compound is essential for laboratories and manufacturers in the pharmaceutical, chemical, and water treatment industries requiring accurate analytical measurements.

Application

• pH Indicator in analytical chemistry and titration procedures.
• Complexometric Indicator for the determination of metal ions such as calcium and magnesium in hardness testing.
• Biological Staining agent in microscopy and histology for tissue visualization.
• Research & Development reagent in biochemical assays and diagnostic kit formulation.
• Water Quality Analysis for monitoring hardness and metal ion concentration in industrial and environmental samples.
• Educational Use as a standard laboratory reagent for teaching analytical chemistry principles.
